. Each of thesefshalf'ts `10a*is.delves-ignied, `to

`earry a series. of scraper` membersE which.

comprise. short sections of'beltingv "These beltingmembers. are cut .fro/mathe ordinary steek rubberbelting. .f .Riveted to. one aceefthe belting il is 'a series of sera'per plates 12,"ene fof; said pilates being `placed neary eaeh side? edge and adjra.- i

Thesebelts are-,usually provided with two other plates still nearer the'aeentralfportion at' the .belt 11 andy in line. withjthe first. tivo. 4 plates,4 mentioned.; Thesel have `dispense.d

ber le and the. members lrandln n Eaehe the end. members et. the nangee 181, is previded with. epeninrrs fen :the-pars pose f; receiving snitabl-e, belts 1 9'. The Seid langes 18.y .are elampedtegether,as

shown in Figure 3, by means of said bolts 19.

Each ofthe members 16 is designed to carry the inner end of a belting member 11 which is secured in position by means of bolts 2O extending vthrough the member 15 of one of themembers 13, and through the member 16 of the adjacent member. A plate 21 is then placed over the inner end of Jhe belt 11 on the opposite face from that engaged; by the member 16 and held in position ,bymeans of nuts 22 on the bolts 20. This provides means for rigidly clamping the inner end of the belt to the mem-` yis detached and the bolts removed. This is an important feature in devices of this kind due to the fact that the members 13 may be alined on the shaft andplaced in proper position thereon, after which they f do not have to be removed, and by this i metalfrom which the shaft is built.

method of clampinor the said members`13 will'be securely helcl against rotation on the shaft without having to cut key seats or by boring holes for securing the same'. in position, as the holes cause crystallization of lhe T is crystallization would cause the shaft to be easily broken. These shafts are of a considerable length without any support between their ends, and for that reason con-V siderable bending orr deflection is apparent at the central portion ofthe shafts as they are operated.

I am aware that plates have been provided for mounting the inner end of the member 11 to the members 16, but these plates are very narrow and of a width less than the width of Jhe said members 16. The belts are rotated in a counter-clockwise direction, as shown in Figures 2 and 3, which causes them to be bent over the rounded member 17 as they engage the carcass to be scraped. When the belting disengages the carcass, thel momentum of the members'12k and the weight of the belting 11 will cause the end of the members 16. The reversing the free end vof said belting to be thrown forwardly, as shown in dotted lines in Figure 3.'. This causes avery distinct kink in the belting at a point substantially near of the belt in one direction or the other to such al large angle, will cause the destruction at that point, and I have found that by extending the plate'21 to a point beyond the end of the member 16 and then curving the saidplate forwardly, as shown in Figure 2, that the vforward movement 'of the free end of thev belting 1l; may bevconsiderably modified, and that bent portion of the belt may be made to assume a longer curvature,

and thereby avoid the destructive effectproy duced by the shortkink or curve.

` The plate 21 is curved slightly towards the members 17 at 23, thence curvedk in the opposite direction. vThis has a tendency to hold the backward curved portion of the belt slightly in its backward direction, and

thereby prevent that portion of the belt,

which usually breaks, from being reversed.

The member 21 is ofsuch a length that'y the curved portion of the said member as sumes the portion taken by the plates of the belting 11, which have beenomitted as above referred to. 'y

Il have found by actual practice that these form the same function that the other plates would,` and at the same time eliminate "part` of the weight from the belting l1, and thereby reduces the forward lmomentum above referred' to. I

I .have provided a slot'24rfi-n the central v fact that that portion ofthe belting which f rests between the curvedfends ofthe plate 21 does not bendas abruptlyasthat portion of the belting which engage the said curved portion, and I have found by actualpractice that that portion of the'doelting whichengages the curvedportion of the plate'bre'aks before he centralportionof the'belt'which is opposite the slot 211; The life-of ther` belting is thereby .considerably increased,fas it will still operate'after the-edges ofthe belting have become partiallybroken.-v

\ Thus it will be seen that I haveprovided an improved attachment for beaters for hog scraping machine/which If have Ifound by actual practice tov increase vthe life. of the belting member about four or-fiveitimes', and at the same time providesvfmeansfor rigidly holding the-same to thesha-ft with' out the cutting of key seats or bolt' holes through the shaft. K Iclaim as my invention: 1. The combination of a rotary shaft, a

supporting bracket thereon `provided' with I' a series of radial supporting plates, va beater belt secured to the forward face yof each of said supporting plates,y an' auxiliary plate adjacent toy the forward facefof said belt,y

means for securing said supporting plate, said belt and said auxiliarypl'atestogether, the last saidplatebeing of a length slightly greaterv than'the t length of the lirstsaid plate and provided with a forwardly extending curved lportionv at its outer end. 2. The combinatiOIlQf af lotatively mounted shaft, a supporting bracket formed in a series of cylindrical segments, each of which is provided at one of its longitudinal edges with a radial flange and the other with a radial supporting plate, a beater belt adj acent to the forward face of said supporting plate, an auxiliary plate secured tothe foryio ward face of said beaterv belt opposite said supporting plate, said auxiliary plate being of a length slightly greater than the length ofv said supporting plate and provided with a forwardly and outwardly extending curved end portion, the radial flange of one bracket member being adj aeent to the supporting flange of the adjacent bracket member, bolts extending through said flanges and said supporting plate, said belt and saidauxiliary plate, a nut for each of Said bolts.

3. The combination of a rotatively mounted shaft, a-bracket on said shaft having a series of supporting plates, a radially arranged beater. belt for each of said support, ing plates, means for securing said belt to said support, said belt being designed to r' bend backwardly at the outer end of said support as it engages articles operated on,

' means located on the front side of said belt f curved `portion designed to form scraper blades, said curved portions being separated from each other -to form a central slot, the jy last said plate being of alengtlr slightly greater than the length of the first said plate, and means for securing said platesl and said belts together.

5. The combination of a rotatively mounted shaft, a bracket thereony provided with,` `a series kof radially mounted supporting plates, a flexible beater belt for eachof said plates provided at its free end with scraper blades, a detachable plateI secured to the forward side of said beater belt opposite said support and provided at its outer end with an outwardly and rearwardly extend- 6. The combinationvof a rotary shaft, a"

supporting b-racket thereon, provided` with a series of radial supporting plates, a beater belt secured to the forwardface of each of said plates, an auxiliary plate adjacent to the'forward face of said beater belt, saidA plate being kprovided with a forwardly.ex' .v tending curved portion to form L scraper blades, saidbeater belt being comparatively short and provided'with a `double set'of scraper blades arranged in inner` and outer rows, the inner one of. said blades being lo- `cated adjacent to the outer end of ,said auxiliary plateinsuch a mannerthat the` outer end of said yauxiliaryplate and said.

scraper yblades will 'operate in conjunction with each other toform ascraper member as the said shaft is rotated. f
